Q347f Fixed Turbine Ball Valve
Three split connection forged steel fixed ball valve, the valve body in the two seat along the vertical axis with the valve channel section is divided into three parts, the whole valve along the stem intermediate shaft symmetry, it is important in the pipeline for cutting off, distribution and change the direction of media flow. Under high pressure the right middle position to ensure the ball pivot structure of it, to ensure that the valve operation with excellent performance; standard seat with the spring structure, will push the ball seat, to ensure the excellent import and export of two-way sealing performance; the exercise of built-in discharge valve, the valve in the cavity can be discharged; blow out proof structure cherished by a pivot and effectively prevent leakage; bearing low coefficient of friction, the torque reduction to a minimum, so the valve opening and closing the valve rod and the valve body; useful contact, the electrostatic grounding assembly performance superior etc.. It has many advantages, such as excellent performance, high reliability, wide use and reasonable price.
It is suitable for chemical, petroleum, natural gas, metallurgy and other industries, as well as natural gas long-distance pipeline containing hydrogen sulfide medium, impurities and corrosion.
